摘要： An error in judgment due to the difference in the temperature of the refrigerant at an outlet of a condenser is reduced when judging the adequacy of the refrigerant quantity. An air conditioner (1) includes a refrigerant circuit (10), operation controlling means, and refrigerant quantity judging means. The refrigerant circuit (10) is configured by the interconnection of a compressor (21), an outdoor heat exchanger (23), a subcooler (25), an indoor expansion valve (41, 51), and an indoor heat exchanger (42, 52). The operation controlling means can perform a refrigerant quantity judging operation in which performance of the subcooler (25) is controlled such that the temperature of the refrigerant sent from the subcooler (25) to the indoor expansion valve (41, 51) becomes constant. The refrigerant quantity judging means judges the adequacy of the refrigerant quantity in the refrigerant circuit (10) based on an operation state quantity of constituent equipment or refrigerant flowing in the refrigerant circuit (10) in the refrigerant quantity judging operation.

摘要： In a multi-type air conditioner, the adequacy of the refrigerant quantity charged in the air conditioner can be accurately determined, even when the refrigerant quantity charged on site is inconsistent, or even when a reference value of the operation state quantity, which is used for determining the adequacy of the refrigerant quantity, fluctuates depending on the pipe length of the refrigerant communication pipe, combination of utilization units, and the difference in the installation height among each unit. In an air conditioner (1) including a refrigerant circuit (10) configured by the interconnection of a heat source unit (2) and utilization units (4, 5) via refrigerant communication pipes (6, 7), a refrigerant quantity determining system determines the adequacy of the refrigerant quantity and includes a state quantity storing means and a refrigerant quantity determining means. The state quantity storing means stores the operation state quantity of constituent equipment or the refrigerant flowing in the refrigerant circuit (10) in which refrigerant is charged up to an initial refrigerant quantity by on-site refrigerant charging. The refrigerant quantity determining means compares the operation state quantity during test operation as a reference value with a current value of the operation state quantity, and thereby determines the adequacy of the refrigerant quantity.

摘要： An air conditioner is provided with a refrigerant circuit, refrigerant stagnation judging means, and an operation controller. The refrigerant circuit is a circuit that includes a heat source unit, a refrigerant communication pipe, an expansion mechanism, and a utilization unit. A heat source unit and a utilization unit are connected to the refrigerant fluid communication pipes. The heat source unit has a compression mechanism and a heat source side heat exchanger. The refrigerant stagnation judging means can judge whether the refrigerant has stagnated inside the compression mechanism. The operation controller performs a refrigerant de-stagnation operation for eliminating stagnation of the refrigerant in the case that the refrigerant stagnation judging means has judged in advance that the refrigerant inside the compression mechanism has stagnated when a refrigerant quantity judging operation is carried out for judging the refrigerant quantity inside the refrigerant circuit.
